| Sony | KV27V22 AA-2 | CONVERGENCE | KV27V22 serial # 8051260 will not converge the bottom red green or blue horizontal lines | Unit has over 6 permaloy magnetic on the CRT bell in the area of the bottom of the yoke. This is not a good sign. It is also a rebuilt CRT. We are not going to place more Permaloy strips on this CRT. It needs replacement. | Muller |
| Sony | KV32V15 AA-2 | color banding | Sony KV32V15 serial 9013716 AA-2D Unit has horizontal banding of purple and red at top of screen. If the color was reduced the banding would disappear. Color bar did not have a normal appearance | Resistor R354 was not soldered in correctly. The resistor is in the Color AFC circuitry. It had a .15 ms ripple on it causing a phase shift in the chroma in the first 4 to 5 inches on the picture. Problem was caused by a glue used to secure the surface mounted resistor. The glue prevented a good connection of the resistor to the pad. Cleaning the glue away and resoldering corrected the symptom. | Muller |
| Sony | KV27V20 AA-2 | CLOSED CAPTION | Sony KV27V20.unit has intermittent symptom of closed caption coming up on screen. Cust claims they cannot turn off the closed caption option. | Unable to see any problem with circuitry, and ID codes are correct. All appears normal. Setting all CC1 ~ CC4 and teletext 1 and 2 to the ""Minus"" option this effectively shuts off the closes caption feature. Instruct customer to operation od "" | Muller |
| Sony | KV27V20 AA-2 | CLOSED CAPTION | No closed caption on premium channels | The tech needs to set the ID codes to the following ID0=25, ID1=19, ID2=47, ID3=0, ID4=27, ID5=3, ID6=0, ID7=0. If these are OK then the tech will need to replace the IC001 with an upgraded version per bulletin 329R1 Original generic # is CXP85640-004S, the new generic # is CXP856P40S-1 part number T-935-001-61 | Muller |
| Sony | KV35V75 AA-2 | CLOSED CAPTION | KV35V75 9006691 Unit does not have closed caption on premium channels | Original CPU CXP85640-005S The new device is CXP85640006S CPU was replaced and did not correct the symptom. | Muller |
| Sony | KV27V20 AA-2 | CLOSED CAPTION | KV27V20 serial 8015729 Unit does not have closed caption on premium channels | See Bulletin 329R Original CPU CXP85640-005S The new device is CXP85640-006S | Muller |
| Sony | KV27V20 AA-2 | CLOSED CAPTION | KV27V20 8015729 No closed caption on premium channels | these are OK then the tech will need to replace the IC001 with an upgraded version per bulletin 329R1 Original generic | Muller |
| Sony | KV27S20 AA-2 | CLOSED CAPTION | KV27S20 serial # 7042141 Unit will not operate in the closed caption mode if using the DVD player. However if the television operates in the tuner mode for over the air telecasts, closed caption works fine. | Tech needs to order IC001= T-935-001-61 per bulletin R329R1. After replacement the tech will need to enter the tech menu and select ""CRIW"" and change it from 15 to 3. Also check the ""LBLK"" must be 7, ""RBLK"" must be 7 and ""HBSWO"" must be 0. At this point save the new data and "" | Muller |
| Sony | KV35XBR48 AA-2 | CHROMA | Unit is connected in to component video input mode through a DVD player. The picture has a predominately green picture | When operating a different DVD player the symptom is the same. There is no cure to this phenomin from Sony at this time | Muller |
| Sony | KV35XBR20 0 AA-2 | CHROMA | KV36XBR200 When the customer is using the RF input labeled VHF/UHF the set will picture will lose chroma intermittently. But when using the AUX input the chroma is solid and does not vary. The tech replaced the RF switch without effecting the symptom. | The customer is using two different RF sources. Cable TV and a satellite dish. The CATV is being feed into the RF input labeled VHF/UHF and the satellite is fed into the AUX input. It appears the tuner does not correct the AFT when two different RF sources are used. The channel will has to be readdressed again for any AFT correction to occur. Suggest the customer used the satellite in the S-video and separate video input mode. In his present configuration the customer is loosing all stereo reception, and all high frequency detail over. This corrected the symptom. | Muller |
| Sony | KV35S26 AA-2 | chroma | KV35S36. Unit has random chroma phase shifting. The tint will vary radically. NTSC color bars are not stable. ""Barber Polling"" effect of colors on bars. "" | Suggest the tech look very close to the connection s to IC351(4) This the Chroma AFDC filter. Components R354, C355, C355 are in the AFCFIL circuit. It is possible the trouble is a Jungle IC but Before replacing it is recommended to check the aforementioned components first. Note: when checking the components it was found that C366 has glue touching each end of the device. The glue effectively changed the value of the device. Cleaning the glue and reinstalling the device corrected the problem. | Muller |
| Sony | KV35S26 AA-2 | CHROMA | KV35S26 Unit has the tint phase shift and color lock up problems only on the Hughs satellite receiver. VCR and over air signals have solid color lock up. | This symptom acts like it is a problem with the satellite receiver. Inside the satellite receiver there is a NTSC encoder which injects the 3.579547 MHz color oscillator signal in the video. If this oscillator is too far off frequency it will not phase lock with the 3.579545 MHz in the television. This is a software problem with the Satalite receiver. A software download will be available to all receivers in Late | Muller |
| Sony | KV27S22 AA-2 | BRIGHT RASTER | KV27S22 serial # 8102548. Unit goes to a bright blue screen with retrace lines then shuts down. | Unit has a defective CRT. When unit is able to turn back on again the set will sometimes be in the video input mode. | Muller |
| Sony | KV35XBR35 AA-2 | B&W Tracking | KV35XBR35. Unit has color temperature error in the YUV input mode only | According to Sony tech support there is no adjustment for this input. Refer this customer to Sony customer affairs. | Muller |
| Sony | KV27V65 AA-2 | audio | Sony KV27V65 Sound does not ramp up correctly. Seems to get very loud as soon as the volume gets higher in a very short time | I had tech get into the ID codes and reset ID2 from 239 to 175 and ID 4 from 130 to 194. Then initialize the EPROM . Set returned to normal operation | Muller |
